STEADYING DEVICE FORGAS-DISTRIBUTING SYSTEMS.

SPECIFICATION forming part of Letters Patent N0. 765,925, dated July 26, 1904.

Application filed March 12, 1904.

To all whom it may concern.-

Be it known that we, GIDEoN R. IBAoH, residing at Brooklyn, county of Kings, and EMIL J. BARTEL, residing at Long Island, county of Queens, State of NewYork, citizens of the United States, have invented a Steadying Device for Gas Systems, of which the following is a specification.

Our invention has for its object the production of a device to be employed in gas-lighting systems wherein it is also desired to run an ordinary gas-engine, the purpose of such device being to enable the user to employ a single meter and system for the two purposes and yet to prevent the pulsations of the engine in any way influencing the steady flow of gas to the lighting system. 'Heretofore I under such conditions it has been found that and valve removed.

in attempting to operate a lighting system and a gas-engine by means of gas conducted through the same service-pipes the pulsations of the engine (commonly called the suck) caused the gas to be fed unsteadily to the burners, so that the lights would rise and fall. This necessitated employing different meters and systems-one for the lighting system and the other for the engine. The invention therefore consists in the employment of a device for the purpose stated between the usual house-meter and the engine and in the device hereinafter described. Referring to the drawings, Figure 1 illustrates in elevation a meter, a gas-engine, a house-lighting system, and our improved device located between the meter and engine. Fig. 2 is a detail in vertical longitudinal section of our improved device. Fig. 3 is a top plan view of the latter device with the cap Fig. 1 is a detail in plan of the removed valve, and Fig. 5 is a transverse section of the same.

Similar numerals of reference indicate similar parts in all the figures of the drawings.

In the drawings, 1- designates the meter; 2, the gas-engine; 3, the pipe leading from the former to the latter; 1, the pipe leading to the house-lighting system; 5, the gas-bag or other form of pressure device, and 6 our device for overcoming the pulsations of the engine with- Serial No. 197.748. (N0 model.)

in the house-lighting system, said device being located between the engine and the point in the pipe 3 at which the pipe supplying the lighting system is connected.

Our steadying device comprises a preferably circular shell 7 provided with an upwardly-disposed interiorly-threaded flange 8, surmounted by a removable dome-shaped cap or cover 9, which after such removal affords a means of access to the interior of the device to facilitate cleaning, repair, &c.

Cast integral with the shell 7 or otherwise secured therein is a centrally-located cylindrical shell forming a central port 10, provided at its upper end with a valve-seat'lO and at its lower end with a similar seat 11.

A vertical wall 12, annular in shape, surrounds the port 10 and may be eXteriorly threaded for a purpose hereinafter apparent. This wall 12 rises from a horizontal partition 13, which serves to subdivide the shell 7.

Between the shell forming the portlO and the short annular vertical wall 12 is formed an annular chamber 14:, the same being produced by the two intermediate substantially horizontal walls 15 and 16. The chamber thus produced has its upper wall or dome provided with an external channel 17, which therefore surrounds the port 10, and said wall or dome 15 is at intervals provided with ports 18, afiording a means of communication between the channel 17, and therefore the port 10 and the annular chamber.

The upper edge of the short vertical wall 12, that surrounds the channel 17 is finished off to form a valve-seat 19, the latter being in 85 the same horizontal plane as the upper seat 10 of the port 10. These two valve-seats 10 and 19 are covered by the same clack-valve or diaphragm 20, (for detail of which see Figs. 1 and 5,) and the same may consist of a light leather or other body 21, surmounted by a metal disk 22 above the seat 10 and a metal ring 23 above the seat 19, said disk and ring lending stability and assuring a complete closing of the valve upon the two seats.

To retain the valve in operative position upon the seats, we may provide a flanged ring 2 1, the flanged wall of which is internally threaded to engage the threads of the annular vertical Wall 12.

The bottom of the main shell 7 may be formed with an opening 25, into which is threaded a plug or plate 26, designed to be removed to afford access to the shell 6 for the purpose of producing the lower seat 11 of the central port 10. This plug 26 may have a central perforation 27, in which is adjustably threaded a valve-stem 28, the lower end of the latter carrying an operating hand-wheel 29 and the upper end a valve 30, adapted to be adjusted with relation to the seat 11 of the port 10.

At opposite sides of the shell 7 are located branch pipes 31 and 32, the former being the inlet branch and communicating with the annular chamber 14 and the remaining being the outlet branch and communicating with the shell 7 below the port 10 or, in other words, the outlet-chamber 33. Of course the ends of these pipes may be finished in any way to adapt them for coupling up with the servicepipe 3.

The valve 30 may or may not be employed; but we prefer to do so. This valve, if em-. ployed, is of course adjusted to the wants of the engine.

The gas coming from the meter passes to the pipes 3 and 4. In passing through the former the gas passes through our steadying device, first entering through the inlet branch thereof and passing out through the outlet branch. in passing from the inlet branch 31 the gas flows into the annular chamber 14, passing up through the ports or perforations 18 into the channel 17. The pressure is suflicient to raise the valve 20, thus permitting the gas to descend through the port 10 into the chamber 33 and from thence out. This describes the usual flow of gas, or, in other words, when the gas-bag or other form of pressure-equalizer is full. Immediately, however, that the suck of the engine is capable of being felt in the service-pipe between the pressure-equalizer and the meter, and therefore in the lighting-system pipe 4, the suction is sufiicient to close the valve 20, which cuts off communication between the house-lighting system and the engine, so that the former is not in the least affected. In this manner the undesirable flicker of the lights is avoided and yet at the same time the one gas system can be utilized to serve the two systems.

Various changes may be made in our invention as regards the details of construction, and we therefore would have it understood that we do not confine our invention to the precise details herein shown and described.
